I uploaded one video to youtube a month back, to promote one affiliate product, the keyword was of medium competition with 18k searches. Anyway I built good quality links from blog networks(which has worked exceptionally in the past), I did social bookmarking for the video, I bought some social signals, video has likes, subscribers and views too. Technically speaking my video has way better links(both in quality & quantity) than other ranking videos. However after one month also, my video is not showing anywhere in SERPs, yes it is indexed, but it not showing up in SERPs, it is weird and I have never experienced this. Can anyone provide possible solution for the same.
